Heat-Sink Insulator Silicone Rubber

Agate & Agate offer heat-conducting and electrically insulating silicone rubber punched parts or sheets. These are used for effective electrical insulation of power semiconductor devices from the heat-sink surface. The silicone rubber sheet is also a good conductor of heat and allows steady heat dissipation from the power semiconductor to the heat-sink body. Being rubber, it conforms to the heat-sink and power semiconductor surfaces in contact and does not allow any air-gaps between the two surfaces, thereby providing perfect medium for heat conduction. Its electrical insulation property combined with heat dissipation characteristic makes it an ideal replacement for available conventional mica and heat-sink compound combination. This fire retardant silicone rubber demonstrates a stable electrical and thermal performance over a wide temperature range of 600C to 1800C. It is available in 0.3 mm thickness and can withstand voltage up to 4 kV. Its coefficient of thermal conduction is 3 x 10-3 cal/cm see 0C. It is available in punched parts in TO220, TO3P, TO3 shapes and in a roll form with 1 ft fixed width. Extruded tubes in various diameters are also available in this material.
